Acute respiratory distress syndrome is a type of respiratory failure characterized by rapid inset of widspread inflammation in the lungs. Symptomes include shortness of breath, eapid breathing and bluish skin coloration. Causes may include sepsis, pancrease, trauma, pneumonia, and aspiration.
ARDS is uniformly associated with pulmonary hypertension. Pulmonary artery vasoconstriction likely contributes to ventilation-perfusion mismatch and is one of the mechanism of hypoxemia of in ARDS. Normalization of pulmonary artey pressure occures as the syndrome resolves.
